    One-sixth of a number when subtracted from the number itself gives 25. The number is

    A)  30      

    B)         32      

    C)  35                  

    D)         28

    Correct Answer: A

    Solution :

            Let the number be\[x\] According to question, we have \[x-\frac{1}{6}x=25\Rightarrow \frac{6x-x}{6}=25\] \[\Rightarrow 5x=25\times 6\Rightarrow x=\frac{25\times 6}{5}\Rightarrow x=30\] So, the number is 30.
